Description

Loudspeaker fixed knot of balance car constructs and balance car

Technical Field

The invention relates to the field of balance cars, in particular to a horn fixing structure of a balance car and the balance car.

Background

The balance car is a high-tech intelligent product which utilizes the dynamic balance principle to control the forward and backward movement. The running speed and the advancing direction of the balance car can be controlled along with the inclination of the body. The current balance vehicle mainly comprises a single-wheel balance vehicle and a double-wheel balance vehicle. The double-wheel balance car is particularly popular with consumers because of high stability and simple driving.

The double round balance car generally includes the automobile body, and the automobile body is including setting up in the lower casing of automobile body downside, installs loudspeaker on the lower casing, and loudspeaker pass through sticky mode and paste on the casing down. The balance car sends out sound through the loudspeaker and reminds the user of the state that the balance car is located.

In current double round balance car structure, loudspeaker pass through sticky mode paste down on the casing, loudspeaker can drop and damage from casing down after the balance car receives the striking, and rocking of loudspeaker of damage in the automobile body can further destroy other parts, seriously influences the security performance of balance car. The existing adhesive fastening is therefore extremely unstable.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a horn fixing structure of a balance car for stably fixing a horn and the balance car.

The purpose of the invention is realized by the following technical scheme:

a horn fixing structure of a balance car comprises a car body, wherein the car body comprises a lower shell, a horn and a horn fixing structure;

the loudspeaker fixed knot constructs includes:

the supporting frame is arranged on the vehicle body;

the protective cover is matched with the fixing ring;

wherein, the support frame with the protective cover cooperatees and fixes loudspeaker under on the casing.

Optionally, the support frame includes first ring and second ring, first ring is located the second ring outside, the inner ring face of first ring is less than the inner ring face of second ring, first ring with form first ring face between the second ring, loudspeaker include the loudspeaker outer loop, first ring face with the loudspeaker outer loop cooperatees. Like this, first ring surface and loudspeaker outer loop cooperate, and first ring surface can restrict loudspeaker axial's removal, and the radial removal of loudspeaker can be restricted to the second ring, can effectively restrict loudspeaker's axial and radial movement through first ring and second ring for loudspeaker's fixed more firm.

Optionally, the lower shell includes a first opening, the support frame is fixed to be established on the inner surface of the lower shell, and the support frame is arranged along the edge shape fit of the first opening. Like this, the installation and the dismantlement of loudspeaker are made things convenient for in first open-ended setting, and the inferior valve physical stamina can effectually protect the support frame, better protects loudspeaker.

Optionally, the protective cover includes a cover plate, the first opening includes a circular opening, the cover plate is matched with the first opening, and the diameter of the first cover plate is smaller than that of the circular opening. Therefore, the circular opening is concentric with the support frame, so that the loudspeaker can be installed from the center of the circular opening when being installed, and the falling position is just the center of the support frame.

Optionally, the protective cover includes lid hook and lid and detains, the lid hook with the lid is detained and is located respectively the both ends of apron, the lid hook with the lid detain with lower casing phase cooperation. Like this, lid hook and lid buckle catch the casing down, and support the both ends of protective cover for the protective cover is fixed on casing down, is difficult for droing.

Optionally, a cover hook groove and a cover buckle groove are formed in the second circular ring, the cover hook is matched and fixed with the cover hook groove, and the cover buckle is matched and fixed with the cover buckle groove. Like this, because lid hook and lid are detained and are located the both ends of apron respectively, lid hook slot and lid are detained the groove and also can separately arrange, and the influence that the divided groove brought second ring intensity is less.

Optionally, the cover hook comprises a first plane and a first curved surface, the first plane is matched with the inner surface of the lower shell, and the first curved surface is matched with the inner surface of the cover hook groove. Therefore, the first curved surface can slide in the cover hook groove when the cover hook is installed, and cannot be clamped; the first plane can ensure that the protective cover is attached to the inner surface of the lower shell after being installed, and the protective cover is fixed.

Optionally, the cover buckle comprises a first buckle plate and a second buckle plate, the first buckle plate is connected with the cover plate, the second buckle plate comprises a buckle end, the buckle end is matched with the cover buckle groove, and the outer end of the second buckle plate is higher than the outer surface of the lower shell. Like this, when the protective cover dress, the buckle end can get into the lid catching groove, with the cooperation of lid catching groove, the protective cover will be firm fixed under on the casing.

Optionally, the cover plate is a curved plate, and the bending degree of the cover plate is the same as the curvature of the circular opening. Therefore, after the cover plate is installed and fills the gap of the circular opening, the outer side surface of the whole lower shell can be smooth and attractive.

Another object of the present invention is to provide a balance car, which includes a lower housing, a horn and the above-mentioned horn fixing structure, wherein the horn is fixed on the lower housing through the horn fixing structure.

According to the invention, the loudspeaker is fixed through the matching of the support frame and the protective cover, and compared with a gluing mode, the mode of connecting the loudspeaker and the lower shell together through the loudspeaker fixing structure is more stable; the support frame can cooperate with loudspeaker, and accessible support frame location during loudspeaker installation, support frame and protective cover cooperation locking can be fixed loudspeaker on lower casing, make it be difficult for droing.
